Industrial Applications of Laser-Based Profilometry

Industrial applications of laser-based profilometry have rapidly evolved over the past ten years. During this time, QUEST Integrated, Inc., has been actively involved in developing systems for a wide variety of NDE and quality control applications. Employing the principle of optical triangulation, sensors have been developed for applications ranging from measuring 0.25-inch-diameter tubing to mapping a 24-inch-diameter nozzle 70 feet underwater. Three-dimensional contour maps can be rapidly and accurately generated that allow operators to obtain quantitative information regarding the condition of test articles
